How an electric lift works

The elevator is a comfort of no small account within buildings, as it allows the vertical movement of people and things, making it particularly possible to do so for the benefit of those who are oppressed by reduced mobility.

When you decide to install one, you must choose between the various types of lift on the market and you must do so bearing in mind the context in which the device will operate. As for those characterized by very pronounced traffic and which must be disposed of quickly, for example public offices, hospitals, hotels or business centers, the ideal solution can be represented by the electric lift. So let’s take a closer look at what it is and how it works.

elettrico_06What is  electric lifts?

For electric lifts we mean those that are operated by a winch, which has the task of transmitting the motion to the cabin through the adherence of the ropes and served by a motor which must necessarily be positioned on the top of the shaft. This is precisely the reason why the positioning of the machine room must be foreseen during the design stage, within which the winch and control panel must be located at the top of the shaft. To provide for the loads supported must then be the insole that goes to delimit the upper end of the compartment. Usually the electric lifts are equipped with an inverter which allows to adjust all the parameters of the ride.

How an electric lift works

If we have seen from a purely technical point of view what an electric lift is, a separate chapter is the one due to its operation, which takes place thanks to the work expressed by a winch, or an electric traction lifting machine which provides to transmit the movement of ascent or descent to the ropes that connect the cabin to a counterweight. Usually this counterweight is the effect of a calculation that sees the addition to the weight of the cabin of half the same capacity. As far as the engine is concerned, it can be with or without gearless gear.

In the new generation platforms, the lifting machinery is positioned inside the cab compartment, making the presence of a specifically dedicated room no longer necessary.

It should also be remembered that contrary to what is thought, this type of machinery also enjoys the supply of ropes, with the exception of those who are called to serve a limited number of floors.

What are the advantages of the electric lift

Naturally when considering the idea of ​​installing a lift, it is necessary to take into consideration the merits and defects that characterize each type. As for electric lifts, the advantages offered are as follows:

– lower electricity consumption;

– relatively low operating costs;

– the lack of presence of polluting materials;

– the speed that characterizes the system;

– the comfort that characterizes the rides made by the lift;

– the ability to align better with the plane compared to competing machines;

– the ability to continue to operate even in the event of an interruption in the supply of electricity, with a consequent blackout;

– the possibility of saving space which usually must be destined for the machine room which, if it already exists, can be recovered in order to be destined for other use

What are the disadvantages of the electric lift

Given the advantages shown on the other side of the scale, it is naturally necessary to put the defects in order to proceed with a choice that is more oriented towards the starting requirements. Among these, it should be noted above all a purchase cost that may be slightly higher than that proposed by other solutions.
